How many milliliters of water does a person drink a day?

Adults with light physical activity should drink at least 1200 ml of water every day. Take a 200 ml cup as an example, that is 6 glasses of water.

In fact, for healthy people, there is no upper limit for the total amount of water to drink every day. This is because people's kidneys are very strong, and the water they drink can be discharged even if it is more than necessary. Of course, if you drink too much at once and exceed the renal excretion rate (about 0.7 ~ 1.0 liter/hour), it will cause water poisoning.

In addition, people with heart and kidney diseases should not drink too much water, which will add unnecessary burden to these diseased organs.

According to the Dietary Guide for China Residents, healthy adults need about 2,500 ml of water every day. Considering the moisture in food, the guide suggests that adults with mild physical activity should drink at least 65,438+0,200 ml of water every day under mild climate conditions. Take a 200ml cup as an example, that is 6 glasses of water. If the momentum of physical activity is high, or the ambient temperature is high, then drink more water.

In addition, the guide also points out that drinking water should be less and more often, and the drinking time should be allocated to any time of the day, with each time being about 200 ml (1 cup). In this way, it is enough for people who work in the office or students in class to drink half a cup to a glass of water every hour or so, and then drink one or two cups when they go home to rest.

Drinking water like this is healthy.

1, took a sip of water.

When thirsty, many people are used to gulping water. As we all know, this way of drinking water is not good for your health. Small amount, multiple times and slow drinking are three basic principles.

There are three possible consequences of swigging water: first, drinking a lot of water at once will dilute the blood quickly and increase the burden on the heart. After the exercise, this situation became more serious.

Secondly, when sweating heavily in hot days, binge drinking will increase the amount of perspiration reflexively, further increasing the loss of electrolytes such as sodium and potassium, so people tend to drink more and more thirsty.

Third, drinking too fast and too hard will swallow a lot of air together, which is easy to cause hiccups or bloating.

A reasonable way to drink water is to put a mouthful of water in your mouth and slowly swallow it several times, which can fully moisten your mouth and throat and effectively relieve your thirst.

How much water to drink varies from person to person.

Normal and healthy people can judge when to replenish more water by urine color: the normal urine color should be light yellow, and if the color is too dark, it should be supplemented with water; If the color is light, there may be too much water.

For patients, drinking water needs to vary from person to person. For example, patients with heart disease should increase their water intake every day when coronary artery blood supply is insufficient to avoid myocardial infarction due to high blood viscosity. However, when patients have heart failure, they should not drink too much water.

Because drinking too much water will increase the burden on the heart and lead to aggravation of the disease. To avoid increasing the burden on the kidneys, patients with acute nephritis and renal failure should not drink too much water. When people catch a cold and have a fever, the water lost in the respiratory tract is more than usual. In addition, the temperature of fever increases, and the water evaporated from the skin also increases, so it is necessary to replenish water appropriately.
